source for Focomat negative carrier.

I got a Focomat v 35 off ebay. It came with a negative carrier for slides. I suspect I can use it by simply sliding b/w film strips thru a slide holder, i.e the cardboard and make out ok.
Would rather have the holder designed for film strips, however.

That looks like the carrier for a Focomat I / Valoy. Does the V35 use the same carrier?

I'm always astonished at the number of Leitz enlargers that go missing the negative carrier. I can see needing a carrier in a Beseler/Omega 4x5 where the enlargers are used for a half-dozen negative sizes (and carriers are readily available) but a V35 only does 35mm - or do hordes use them for 126 and 16mm?
